Antigens: Definition, Determinants and Immunopotency

The below mentioned article provides a short note on Antigens:- 1. Definition of Antigens 2. Antigenic Determinants 3. Immunopotency. Definition of Antigens: Substances which can give an immune response when introduced into an animal are called immunogens or antigens. Although most antigens are macromolecular proteins, polysaccharides, synthetic polypeptides and other synthetic polymers may also be immunogenic. Although the characteristics of [...]

Compounds Formed from Sugar and Hydroxyl Groups | Carbohydrates

The following points highlight the two main compounds formed from sugar and hydroxyl groups. The compounds are: 1. Glycosides 2. Amino Sugars (Hexosamines). Compound # 1. Glycosides: Glycosides are compounds formed by the conden­sation reaction between a sugar and the hydroxyl group of a second compound or aglycone which may or may not be another sugar. If the carbohy­drate portion [...]

Carbohydrates and Cell Membrane of Mammals

The following points highlight the top three properties of carbohydrates in cell membrane of mammals. 1. The mammalian cell membrane contains about 5 per cent carbohydrates present in glycoproteins and glycolipids. 2. Glycophorin, the major integral mem­brane glycoprotein of human erythrocytes, consists of 130 amino acid residues and spans the lipid membrane having free polypeptide proteins outside both the ex­ternal [...]
